Changes in this standard: Many minor ch

32、anges are introduced due to the harmonisation between the various standards. This includes the definitions that are used. Some definitions are modified as some standards mentioned the same words with a different meaning. The user is advised to compare the text he is used to (including the definition

33、s) with the current version. Most aspects were already introduced for some boiler types, but are now valid for a larger group of boilers. a) Examples of modifications due to harmonisation: 1) Requirements for materials used for the flue function (8.101, 8.102, 8,103); 2) The soundness of the combust

34、ion circuit (8.2.2); b) New or generally reworded requirements: 1) Air proving (5.4.8, 5.4.9, 8.11.101); 2) Adjustment of gas air ration controllers (8.11.101); 3) Risk assessment (11); 4) Auxiliary energy use (10); BS EN 15502-2-1:2012 EN 15502-2-1:2012 (E) Copyright European Committee for Standard

40、red heating boiler is an appliance using gas as fuel designed to heat water with the purpose of providing heat to a building (or portion of a building) from one point to multiple rooms using heat emitters such as radiators and convectors to transmit the heat from the water to the room. The boiler ma

41、y also be used to provide domestic hot water via an indirect hot water storage tank. The basic function of gas-fired heating boiler is to generate heat by direct heat transfer in a heat exchanger, from the combustion gasses to the water. The boiler may include in one design more than one function. I

42、t may include for example: a) a sanitary hot water function; b) a function to supply the combustion air from the outside of the building; c) a function to dispose the combustion products to the outside of the building. The boiler design may be supplied to the market in more than one part. If the boi

43、ler is supplied to the market in multiple parts, the boiler is the assembly of various parts according to the installation instructions. Boilers may be designed to be connected to specific parts of a building. Especially, connection to a chimney and the means of combustion air supply are relevant. T

44、his European Standard was established to deal with aspects related to: d) safety; e) rational use of energy; f) fitness for purpose. Matters related to quality assurance systems, tests during production, and certificates of conformity of auxiliary devices are not dealt with in this series of Europea

45、n Standards. Relationship between this document and EN 15502-1, Gas-fired heating boilers Part 1: General requirements and tests: This European Standard is to be used in conjunction with EN 15502-1:2012 and follows the numbering structure of EN 15502-1:2012. This European Standard refers to clauses

46、of EN 15502-1:2012 or adapts clauses by stating in the corresponding clause: shall be according to EN 15502-1:2012, (clause number) with the following modification shall be according to EN 15502-1:2012, (clause number) with the following addition EN 15502-1:2012, (clause number) is replaced by the f

It should be noted that these clauses and subclauses are not indicated as BS EN 15502-2-1:2012 EN 15502-2-1:2012
